Nice. I have one of MCDP2900 adapters on order. Lets see.

Ah, so the Shuttle DH270 LSPCON can do HDMI 2.0a even though it nowhere says so in the spec/docs (that i could find). Only reports to HDMI2.0 there.
Might be a good indicator for other boxes to also check if 'a' is possible ?!

- HDMI 1.4 doesn't go any higher then 2160p@30Hz and never supports HDR
- DP 1.2 goes up to 2160p@60Hz (or HDMI 2.0a with converter)
- minimum CPU for HDR is 7th generation Core CPU (Aka Kaby Lake) and HD 630 graphics (as I recall).
DP 1.2 does not support HDR (officially), only DP 1.4 introduces it, so theoretically you shouldn't be able to convert DP 1.2 into HDMI 2.0a for HDR because that HDR from 2.0a would require HDR metadata coming from the PC and thus requiring DP 1.4. At least thats how i understand it. And i kinda don't believe it. Hence my confusion.
Yes, the HDR requires >= HD630 seems to be Intels current play, other posts in the kodi forums seem to say this should be mostly a driver issue, not HW, but except for travel boxes i am not so much worried to use atom now, and for travel its kinda unlikely to encounter a HDR or 3D display anyhow.
